Some things in life are certain. Death and taxes and every former contestant on The Bachelor and The Bachelorette will go on to write a book and do everything in their power to promote it.

Desiree Hartsock is no different. But to be fair, she didn't write a tell-all memoir bashing the show and breaking our cold, dead hearts by telling us it was all fake. Because after all, she did meet the love of her life on the damn show and they got married off-air — another thing that's a little unusual about her story.

Hartsock will be in Dallas at 7 p.m. Thursday, June 9, at the Barnes and Noble on Northwest Highway as part of her wedding book book tour. My Fairytale Wedding: Planning Your Dream Wedding Without Breaking The Bank is pretty much what you would expect from a wedding dress designer and former Bachelorette. She explores all the ways brides can save money when planning their big day — something she can relate to considering she didn't have the unlimited budget from ABC.

"We were actually open to [the idea of a television wedding], but it just didn't work out for whatever reason with the network. I'm so glad it didn't," she tells us, "because it did give me the ability to write a book with more personal experience, so I'm able to share my own planning experience and tips and offer some advice for working together and making decisions."

Hartsock says brides often overlook the little things that pile up toward the end of planning a wedding. Think transportation — getting the guests from the hotel to the ceremony to the reception.

"It's really important to know the logistics of that and have the transportation set," she says.

Last time you saw Hartsock was probably during the premiere of Dallas gal JoJo Fletcher's season of The Bachelorette. Hartsock, along with some other veterans of the show, offered Fletcher their wise-beyond-the-cameras advice. Hartsock echoed the same things to us.

"It's all about staying grounded, deciphering between love and lust, and then from there moving forward, being grounded," she says. "[My husband] and I also always stress the importance of getting back into your daily routine because that's really going to help you grow as a couple. Live your day-to-day life and not the fairytale of the show."
